摘　　要：利用多模压缩态理论,研究了由多模复共轭虚相干态、多模复共轭虚相干态的相反态和多模复共轭相干态的线性叠加所组成的一种新型的三态叠加多模薛定谔猫态光场|Ψ^((3))>_q中广义磁场分量的不等幂次高次和压缩特性。结果发现:态|Ψ^((3))>_q是一种典型的三态叠加多模非经典光场;在一定条件下,态|Ψ^((3))>_q的广义磁场分量可呈现出周期性变化的广义非线性不等幂次高次和压缩效应。It is studied systematically that generalized nonlinear unequal-power higher-power sum squeezing properties of generalized magnetic-field component in a new kind of three state superposition multimode Schrdinger-cat state light field which is composed of multimode complex conjugation imaginary coherent state, the contrary state of multimode complex conjugation imaginary coherent state, and multimode complex conjugation coherent state, by utilizing the theory of multimode squeezed states. It is found that the state is a new type of three state superposition multimode nonclassical light field, and under certain conditions, the generalized magnetic-field component in the state can display the effects of generalized nonlinear unequal-power higher-power sum squeezing which changes periodically.
